PHASED ARRAY ANTENNA PROVIDED WITH A CALIBRATION NETWORK

摘要

The invention comprises a phased array antenna comprising a number of waveguide radiators (19) and a power supply system and furthermore comprising a calibration network (20, 21, 22) for providing a test pulse. By directly connecting the calibration network to the waveguide radiators, a more accurate calibration is obtained, which is due to any phase and amplitude errors arising in the waveguide radiators being processed in a calibration algorithm. In a favourable embodiment, the calibration network is designed as a system of waveguides (20, 21, 22).
